Leisure Lake Main Dam dam
Leisure Lake Main Dam
Leisure Lake Main Dam, located in Callaway County, Missouri, is a privately-owned earth dam constructed in 1960 by Leisure Systems Inc. The dam's primary purpose is for recreation, providing a surface area of 46 acres and a normal storage capacity of 2,484 acre-feet. The dam stands at a height of 58 feet and spans 396 feet in length, impounding water from the TR-AUXVASSE CREEK for leisure activities such as fishing and boating.
Despite its age, the dam is in satisfactory condition with a low hazard potential, as indicated by a moderate risk assessment rating. The dam is regulated by the DAM AND RESERVOIR SAFETY PROG under the Missouri state jurisdiction, with regular inspections conducted every 5 years to ensure its structural integrity and safety. In the event of an emergency, the dam has established emergency action plans, although details on their preparation and adherence to guidelines are not readily available.
Water resource and climate enthusiasts will appreciate the unique design of the Leisure Lake Main Dam, its recreational benefits, and the careful oversight provided by state regulators. The dam's location in the St. Louis District adds to its appeal, offering a tranquil escape for visitors while maintaining a commitment to safety and risk management. As a vital component of the local water infrastructure, the Leisure Lake Main Dam serves as a valuable resource for both the community and the surrounding ecosystem.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Leisure Lake Main Dam
Where does the data for Leisure Lake Main Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
